Abstract
UN APARATO PARA ILUMINAR Y TOMAR UNA IMAGEN DE UNA SUPERFICIE QUE INCLUYE UN APARATO PARA ILUMINAR LA SUPERFICIE, UN APARATO PARA TOMAR UNA IMAGEN DE LA SUPERFICIE ILUMINADA Y GENERAL UNA SEÑAL DE SALIDA REPRESENTATIVA DE LA IMAGEN TOMADA Y UN APARATO PARA LIMITAR EL TIEMPO DE EXPOSICION DEL APARATO DE TOMA DE IMAGENES A UN TIEMPO DE EXPOSICION RAPIDA SELECCIONADO INFERIOR A LA VELOCIDAD DE FRECUENCIA DE CUADRO DE VIDEO DEL APARATO DE TOMA DE IMAGENES. EL APARATO DE TOMA DE IMAGENES PUEDE SER UNA CAMARA BASADA EN CCD (40). LA CAMARA BASADA EN CCD Y EL APARATO DE ILUMINACION SE PUEDEN MONTAR EN UN RECUBRIMIENTO (20) QUE TIENE UNA PARED LATERAL OPACA. ENTRE EL APARATO DE ILUMINACION Y LA SUPERFICIE SE PUEDE COLOCAR UNA PRIMERA PELICULA DE POLARIZACION (100) Y ENTRE LA SUPERFICIE Y EL APARATO DE TOMA DE IMAGENES SE PUEDE COLOCAR UNA SEGUNDA PELICULA DE POLARIZACION (102) QUE TIENE UNA ORIENTACION DE POLARIZACION PERPENDICULAR A LA DE LA PRIMERA PELICULA DE POLARIZACION. SE PUEDEN INCLUIR UNOSINTERRUPTORES DE CLAVIJA (130, 132) PARA PREVENIR LA ACTIVACION DEL APARATO DE ILUMINACION Y DEL APARATO DE TOMA DE IMAGENES EXCEPTO CUANDO UN REBORDE INFERIOR DE LA PARED LATERAL DEL RECUBRIMIENTO ENTRA EN CONTACTO CON LA SUPERFICIE.
